Once upon a time the reason was when your .050 gauge bar was worn you could got to .058 and so on. It's more of a sales gimmick now. As far as strength, I have hit frozen aspen cants at 16K with .50 drivers without any problems.
Sorry Red... but if you use Stihl chain, there is zero difference in strength between 050 and 063... same cutters and joiners - just thinned BOTTOM of the tang on 050.

0.050"
Used on mid range saws, strong, able to take some decent power and abuse.
0.063"
Heavy heavy chain, generally 3/8" pitch chain, generally on higher power, higher rpm saws, not likely to fail under high rpm and high loads such as on a 36" bar buried turning the motor 13,500.
A midrange saw needs some beefy links, but not 0.063"....thus the reason for 0.050"
So, using this logic, why are most 3/8 chains found in .050 and most .325 chains found in .063?
...so I guess nearly zero difference in weight also. Ouch.
....
When did Stihl quit making .058 gauge chain? It comes up occasionally on ebay.
Never heard of that, but it makes sense I guess. Ive never been able to give any reason for the existence of 0.058" chain...The other 3, yeah I can rationalize them.

Lake -
I wondered why STIHL chose for a while to machine small holes [reservoirs]in each driver of .063 chain only. "for superior oil lubrication/retension". This is in addition to the OiloMatic channels. [.325 & 3/8"]
In the older Bar & Chain catalog, these holes are not in the .050 chain, .063 only.
Was the .063 driver stronger [wider] to handle the missing metal?
Curious.
They haven't - it's just not sold by them in many parts of North Amercia.
So, using this logic, why are most 3/8 chains found in .050 and most .325 chains found in .063?
I sell one loop of .325/.063 for every 20 I sell of .325/.050
And yes, that is a fact.
